If a car traveling at 80 miles per hour on a slippery road, then its distance D in feet can be caluculated by D=6400/80*1/x, where x is the coefficient of friction between the tires on the road and 0<x>1.
a. Multiply and simplify the fromula for D.
b. Compare the stopping distance on an icy road withh x=0.2 and on dry pavement with x=0.7.
